Hi Lads doing an insulation resistance test and getting a reading of 324.5 ohms on a ring main does anything below 500 ohms need to be rewired?
Thanks
Thanks

It's not quite as simple as "<1M Ohm = Rewire" - there are other factors which need to be taken into consideration which could be causing the low reading, such as equipment (eg surge protector, heater, tv signal booster, anything with a neon on it) plugged in or connected, or even just a poor termination.
It's worth doing some further investigation such as hunting around for hidden equipment (try the loft),and/or splitting the ring and testing each leg, before you go diving in and rewiring the whole property - that kind of behaviour can earn you an undesirable reputation.
